Zero-Temperature Dynamics of ± J Spin Glasses and Related Models
We study zero-temperature, stochastic Ising models σ on Z with (disordered) nearest-neighbor couplings independently chosen from a distribution μ on R and an initial spin configuration chosen uniformly at random. Given d, call μ type I (resp., type F) if, for every x in Z, σ x flips infinitely (resp., only finitely) many times as t → ∞ (with probability one) — or else mixed type M. Models of ty...
متن کاملStatistics of energy levels and zero temperature dynamics for deterministic spin models with glassy behaviour
We consider the zero-temperature dynamics for the infinite-range, non translation invariant one-dimensional spin model introduced by Marinari, Parisi and Ritort to generate glassy behaviour out of a deterministic interaction. It is shown that there can be a large number of metatastable (i.e., one-flip stable) states with very small overlap with the ground state but very close in energy to it, a...
متن کاملComplex Replica Zeros of ±J Ising Spin Glass at Zero Temperature
Zeros of the nth moment of the partition function [Z] are investigated in a vanishing temperature limit β → ∞, n → 0 keeping y = βn ∼ O(1). In this limit, the moment parameterized by y characterizes the distribution of the ground-state energy. We numerically investigate the zeros for ±J Ising spin glass models with tree and other several systems, which can be carried out with a feasible computa...
متن کاملInfluence of Ising - anisotropy on the zero - temperature phase transition in the square lattice spin - 1 2 J − J ′ model
We use a variational mean-field like approach, the coupled cluster method (CCM) and exact diagonalization to investigate the ground-state order-disorder transition for the square lattice spin-half XXZ model with two different nearest-neighbor couplings J and J ′. Increasing J ′ > J the model shows in the isotropic Heisenberg limit a second-order transition from semi-classical Néel order to a qu...
متن کاملInfluence of the spin quantum number s on the zero - temperature phase transition in the square lattice J - J ′ model
We investigate the phase diagram of the Heisenberg antiferromagnet on the square lattice with two different nearest-neighbor bonds J and J ′ (J-J ′ model) at zero temperature. The model exhibits a quantum phase transition at a critical value J ′ c > J between a semi-classically ordered Néel and a magnetically disordered quantum paramagnetic phase of valence-bond type, which is driven by local s...
